This is the Tekin FX-R Rock Crawling ESC and 45 Turn "Heavy Duty" T-Series Brushed Motor Combo. The FX-R reversing speed controller is the industry leader in pure rock crawling performance. With its tiny footprint, improved drag brake resolution with lock-down holding power, adjustable reverse type with reverse delay, no reverse or instant reverse, as well as ultra smooth low speed creep and precision throttle and braking response, the FX-R gives you an edge over the competition. The FX-R has thousands of possible settings right on-board with Tekin's QuickTune Programming and is capable of extensive tuning and updating when used with Tekin's HotWire PC Interface (*not included). The FX-R can also take on your power needs with 3S Li-Po compatibility when used with 35 turn or higher motors. Install the FX-R and step up to smarter, smaller, faster electronics.

Tekin HD "Heavy Duty" T-Series brushed motors feature a new look, improved performance and the same great Tekin quality you know and trust! They are available in the same 35, 45 and 55 turn options as before, but now feature upgraded ferrite magnets to get you wherever you want to go with authority.
